### Orientation Tolerances

The Tutor Orientation Tolerances have the following command formats for Parallelism (PARAL), Perpendicularity (PERPERN) and Angularity (ANGOL):

- PARAL or PERPEN or ANGOL (elchk, eldat)

- PARAL or PERPEN or ANGOL (> eldest, elchk, eldat)

- PARAL or PERPEN or ANGOL DIST(elchk, eldat, dist)

- PARAL or PERPEN or ANGOL DIST(> eldest, elchk, eldat, dist)

- PARAL or PERPEN or ANGOL BOUND (elchk, eldat, boundaries)

- PARAL or PERPEN or ANGOL BOUND (> eldest, elchk, eldat, boundaries)

The arguments for geometric tolerance commands are as follows:

- eldest - Memory that will contain the result. If omitted, the result will be written in the memory of the CHECKED element.

- elchk - Memory in which the CHECKED element is located. It may be an element variable, the element_array variable, or a working storage variable (E.WM1 or E.WM2). If omitted, the E.WM1 is used.

- eldat - Memory in which the DATUM element is held. It can be an element variable, the element_array variable, or a working storage variable (E.WM1 or E.WM2). If omitted, the E.WM1 is used.

- angle - The theoretical angle between the two elements, in degrees and thousandths (for the angularity check only)

- dist - The distance from the checked element baricenter (+and -) which bind the length or area of the element.

- boundaries - Represents a sequence of two or four elements (lines or measured planes constructed or defined theoretically) which bind the length or area of the checked element.

PC-DMIS does not support Boundary elements. The commands that use boundaries and the following Tutor DOS commands are not translated: PARAL (eldat), PERPEN (eldat), & ANGOL (eldat, angle)

Tutor allows the following parallelism, perpendicularity, and Angularity commands:

- Checked Line – Datum Line.

- Checked Line – Datum Plane.

- Checked Plane – Datum Line.

- Checked Plane – Datum Plane.

Where: Line means Class Line feature: Line, Cylinder and Cone.
